Chapter 10 - Quadratic Equations - 10.4 - Solving Quadratic Equations - Which Method? - Problem Set 10.4: 38

Answer

{$14,19$}

Work Step by Step

Factoring the equation and setting the factors equal to zero, we obtain: $x^{2}-33x+266=0$ $x^{2}-14x-19x+266=0$ $x(x-14)-19(x-14)=0$ $(x-14)(x-19)=0$ $(x-14)=0$ or $(x-19)=0$ $x=14$ or $x=19$ Therefore, the solution set is {$14,19$}.
